Answer:
a=3 IF it's continuos
Step-by-step explanation:
for continuity, the left limit of the first equation must be equal to the right limit of the third equation
and they are equal, as you can see putting x=2 in both equations
to be continuos in a point c, f(x) must:
be defined in c (so f(c) exists)
the limit in c exists (in this case both from left and right)
the limit in c must be equal to f(c)
The area of the square will be 640 sq cm.
Step-by-step explanation:
Given,
Number of strip = 4
Length (l) of each strip = 40 cm
Width (b) of each strip = 4 cm
To find the area of the inner square.
Formula
The area of rectangle = l×b
If the area of a square is A, each side will be √A
Now,
Area of each strip = 40×4 sq cm = 160 sq cm
Area of 4 strips = 160×4 sq cm = 640 sq cm
Hence,
The area of the square will be 640 sq cm.
Answer:
B. (1.5, 1.5).
Step-by-step explanation:
Point A has coordinates (-3, -3) and point B is (6, 6).
The mid point is ((-3+6)/2 , (-3+6)/2)
= (3/2 , 3/2)
= (1.5, 1.5) (answer).
Step-by-step explanation:
Answer:
8 Weeks
Step-by-step explanation:
First let's collect the given data:
• <u>Class A:</u>
- Starts at 8 cm
- grows at 3.5 cm/week
• <u>Class B:</u>
- Starts at 10cm
- grows at 3.25 cm/week
Class B's plant starts out 2 cm taller and Class A's plant grows 1/4 cm faster. So, to find when these two will be at an equal height, divide 2 cm by 1/4.
2 ÷ 1/4 =
2 × 4/1 =
2 × 4 =
8
It will take 8 weeks for the plants to be at an equal height.
